But the license of the engine does not allow its
embedding and linking by scripting languages. The GPL
is restrictive in that form.

No, but we are talking about calling IL from perl.

A perls scripting engine cannot call the IL code
without linking into the GPLed code of ILexecute or
its equilvalent (which is crazy to rewrite).

That means then XS modules that contains the ILExecute
as a dll will have to be a GPLed perl module excluding
the usage of any other license in that perl program.
